Can this controller do multiple RAID sets??

Tom Lyczko — Wed, 30 Jul 2014 18:51:53 GMT

I can't find any good information on this...

HP 2GB P-series Smart Array Flash Backed Write Cache(631681-B21)

I need to know if it can do the following within one server:

1 single disk 'array' -- do I use JBOD or RAID 0 or not set it as an array at all??

11 disks in RAID 5 with one (1) global spare

Thank you, Tom

hi ,

The number you provided is from the cache module and not from the controller itself. Please provide info about the controller type.

Thanks

regards,

Controller is P420i embedded.

It does RAID 0 which can take a single disk, the other disks will be done RAID 5 with a global spare.

Thank you, Tom

hi,

The controller + cache can multiple raids. Some useful info can be found in the quickspecs of the controller.

Please keep in mind that the number of discs depends on the server modell. If you want to attach more than 8 drives to the controller, you should have a backplane with integrated sas expander.

Thanks
